Description

Construction method to reduce noise between floors of building {CONSTRUCTION METHOD FOR REDUCING NOISE BETWEEN FLOORS OF BUILDING}

The present invention relates to a construction method for reducing the inter-floor noise that is transmitted from the upper floor in the building to the lower floor, such as apartments or multi-storey building, more specifically, the floor Air passage to reduce the interlayer noise primarily by forming a floor layer and the like to form a space in which the air layer is formed at a predetermined distance from the upper surface of the slab, and then to allow the air of the space in which the air layer is formed on the bottom layer to be circulated The present invention relates to a construction method for remarkably reducing interlayer noise generated in a building by providing a plurality of forming tools so that protruding protrusions are formed in a lattice shape on a lower surface facing the upper surface of the floor slab in the floor layer. .

In the case of a multi-storey building such as an apartment or a double-storey building, if the floor is directly impacted or vibrated by human walking or falling objects, the floor is hardly attenuated, but the floor is lowered through floor slabs, ceilings or walls. It spreads to the floor to generate noise, such floor noise may interfere with the lives of others or, in severe cases, may spread to fight or fight. In particular, since the floor with children runs around, the vibration is transmitted as it is, so that the vibration is transmitted as long as the floor is not buried at the time of construction framing, and the vibration does not occur on the floor to prevent such noise. There was inconvenience such as living by laying a cushioning material such as thick urethane.

Until now, most buildings have used bubbles or shock absorbing materials in Maltar to block the noise, but in the end they act as conductors and live in an environment where the vibration of sound is transmitted to the lower floor.

In order to prevent the noise between floors, nations and construction workers have tried to overcome it through the <Technology> and <Material>, but they have not taken any measures with sound absorption and sound insulation materials (weak effect at 500Hz low band). As a result of the murder, and it became a social issue, the Ministry of Education and Industry is mandating the mandatory provision of increasing the thickness of concrete slabs to 21cm to 25cm for apartments to prevent noise between floors.

However, thickening the slabs in an apartment will add more material by the product of the building's floor area and thickness, and the more material will naturally increase the load, and the overall weight of the building will be heavy. There is a problem that needs to be increased.

On the other hand, many patents and utility models have been applied and registered in order to reduce the noise between floors in apartments and multi-story buildings such as apartments (Patent registration 0493480, 0653596, 0660748, 0729826, 0798892, No. 0827426, etc.) To date, there have been no measures to properly reduce noise between floors in buildings.

The present invention was devised to solve the problems of the prior art as described above, and composed of a floor layer and the like to form a space in which the air layer is formed at regular intervals from the floor slab upper surface in the building as a multi-unit house or a double-storey building 1 The lower surface facing the upper surface of the floor slab in the bottom layer, while installing a plurality of air passage forming holes for automatically reducing the inter-layer noise, and then to distribute the air in the space in which the air layer is formed on the bottom layer. The projecting method for reducing the noise between buildings that can be smoothly and easily constructed for the floor structure for reducing the noise between the floors, which can significantly reduce the noise between the floors, which is formed by the protruding protrusions in a lattice form. The purpose is to provide.

Hereinafter, with reference to the accompanying drawings for the floor structure and the construction method for reducing the noise between the building floor according to the present invention will be described in detail.

The present invention relates to a floor structure and a construction method for reducing the inter-floor noise that the impact sound or noise (hereinafter referred to as? 弩?) Generated in the upper floor in the building as a multi-family apartment or duplex, such as apartments, to the lower floor, Referring to Figures 1 to 5 with respect to the floor structure for noise reduction between buildings according to the invention as follows.

According to the present invention, the floor structure for reducing the noise between floors of a building is divided into a building space in which a floor slab 10 and a wall 20 (including a wall in which a door is installed) are formed perpendicular to the floor slab 10. Applicable

The floor structure for reducing floor noise in the building space in which the floor slab 10 and the wall 20 formed perpendicularly to the floor slab 10 are formed is divided into an upper surface of the floor slab 10 and the wall ( At the point where 20 meets, the inclined bottom support jaw 21 formed along the wall 20 and the inclined bottom support jaw 21 are spaced apart from the top surface of the bottom slab 10 at an interval. The bottom layer 30 etc. which form 33 are comprised.

The floor slab 10 is a floor slab in a reinforced concrete structure building as shown in FIGS. 4A to 4C or a steel frame slab 10a in a steel structure building as shown in FIG. 4D. ) And the slate 10b.

In addition, the wall 20 is a reinforced concrete wall as shown in Figure 4 (a) and (b) or as shown in Figures 4 (c) and (d) stacked bricks, cement blocks, stones, etc. Masonry structure.

The inclined bottom support jaw 21 formed along the wall 20 at the point where the top surface of the bottom slab 10 and the wall 20 meet or the bottom surface of the wall 20 is shown in FIG. As shown in the figure, the construction can be carried out with the construction of reinforced concrete walls, and as shown in FIG. 4 (b), the reinforced concrete or the masonry wall is inclined along the lower surface of the wall 20 after the construction is completed. The bottom support 21a may be attached and formed using a cement paste to achieve a shape, and as shown in FIGS. 4 (c) and 4 (d), the masonry wall may be constructed together at construction. The lower surface of the inclined bottom support jaw 21 may not be attached to the upper surface of the bottom slab 10 to form a gap between the bottom slab 10 and the bottom slab 10.

By forming the bottom support jaw 21 inclined along the lower surface of the wall 20 as described above, when the vibration generated in the bottom layer is transmitted to the wall as shown in Figure 2 the inclined bottom support jaw Due to this is to transmit to the relatively thin upper wall has the advantage of minimizing the vibration transmitted to the lower layer.

The bottom layer 30, which is supported by the inclined bottom support jaw 21 and forms an air layer space 33 at a predetermined distance from the top surface of the bottom slab 10, has a reinforcing bar 35 to increase strength to withstand load. May be disposed in a lattice form to construct cement, sand, gravel, or the like as a mixed cement mortar or concrete. At this time, a heating pipe 34 may be further installed on the bottom layer 30 in a residential or residential building. . In this case, instead of the reinforcing bar 35, a wire mesh may be constructed.

The bottom layer 30 is provided with a plurality of air passage forming holes 32 to allow the air in the air layer space 33 to flow, and facing the upper surface of the bottom slab 10 in the bottom layer 30. Projections 31 are formed which protrude throughout the lower surface. The protrusions 31 formed on the bottom surface of the bottom layer 30 form irregularities on the bottom surface of the bottom layer 30 so as to reduce the speed at which the vibrations are transmitted to the air layer space 33 and reduce the magnitude of the vibrations. It plays a role. The protrusions 31 are long protrusions, preferably in a lattice structure or concentric circles, and preferably have a height of about 10-30 mm.

In order to form the air layer space 33 which forms an air layer at a predetermined interval between the bottom slab 10 and the bottom layer 30, a filler 40 is used during construction, and the construction of the bottom layer 30 is completed. After the through hole 11 is formed in the bottom slab 10 so as to facilitate the discharge of the filler 40 to allow the filler 40 to be discharged through the through hole 11.

By forming the air layer space 33 on the upper surface of the floor slab and the lower surface of the floor layer as described above, the vibration generated in the upper floor layer 30 is not transmitted directly to the floor slab due to the air layer space, the absorption attenuation in the air layer space The noise remaining in the air layer space 33 due to the air passage forming holes 32 is discharged (returned) through the air passage forming holes 32, thereby reducing the interlayer noise. . The air layer space 33 is preferably set to a minimum height of about 10-40mm.

The air passage forming port 32 has a shape as shown in FIG. 5 as a tool for forming an air passage hole in the bottom layer 30 and is installed at the time of construction of the bottom layer 30 to provide air to the bottom layer 30. As the through hole is formed, an air passage forming port cover 32a having a plurality of holes is formed in an upper portion of the air passage forming port 32.

On the other hand, with reference to Figures 6 to 8 with respect to the construction method for the noise reduction between buildings according to the invention as follows.

The inclined floor support jaw 21 may be constructed together with the construction of reinforced concrete walls, as shown in FIG. 4 (a), as described in the floor structure for reducing the noise between buildings. As shown in b), after the construction of the reinforced concrete or the masonry wall is completed, the bottom support 21a is formed by attaching the bottom support 21a using cement paste or the like so that the wall 20 may be inclined according to the floor surface. 4, (c) and (d) as shown in the masonry wall can be installed together at the time of construction.

Next, the filler 40 is laid on the top surface of the bottom slab 10 so that the protrusions 31 are formed on the bottom surface of the bottom layer 30 throughout (see FIG. 6 (b) and FIG. 8 S12). . If the filler (40) is formed in the bottom surface of the bottom layer 30, the filler 40 is covered with a vinyl 41 on the entire surface of the upper surface of the filler 40 when the sand (40a) On the upper surface of the vinyl 41, a long rod made of cement mortar or concrete may be inserted into the filler 40 by a height so that the protrusion 31 is formed vertically and horizontally.

The protrusion 31 formed on the bottom surface of the bottom layer 30 serves to reduce the speed at which the vibration transmitted to the air layer space 33 spreads and reduce the strength of the vibration by forming the unevenness on the bottom surface of the bottom layer. Do it. The protrusion 31 is a long protrusion, which is preferably a lattice structure, a concentric circle, a spiral, or the like, but may be formed in various shapes in some cases.

Next, a plurality of air passage forming holes 32 through which air passes through the upper surface of the filler 40 is disposed, and the reinforcing bar is disposed in the bottom layer 30 as a lattice, and a heating pipe 34 or the like is installed in the bottom layer. Prepare cement mortar or concrete for completion (see Figure 6 (c), Figure 8 S13 step). In this case, the air passage forming hole 32 has a structure in which the lower portion has a relatively large area as shown in FIG. 5 when the cement mortar or concrete is poured on the bottom layer 30 so as not to be conducted. In another embodiment, the air passage forming tool 32 may have a structure in which a lower portion thereof is inserted into and fixed to the filler 40.

Next, when the air passage forming port 32, the heating pipe 34, the reinforcing bar 35, etc. are installed, the cement mortar or concrete is poured and curing is completed. The filler 40 is removed to form an air layer space 33 at a predetermined distance from the top surface of the bottom slab 10 and the bottom layer 30 (see FIGS. 6D, 8 S14 and S15).

When the filler 40 is sand 40a and the bottom layer 30 is completed, a suction mechanism (not shown) is installed in the air passage forming hole 32 to suck the sand 40a which is the filler 40. Or the through hole 11 penetrating the bottom slab 10 to remove the sand 40a, which is the filler 40, through the through hole 11.

On the other hand, as shown in FIG. 7 (a), the filler 40 may be replaced by the uneven styrofoam 40b having the unevenness, and in this case, the protrusion 31 due to the uneven groove of the uneven styrofoam 40b. It is possible to form, the uneven styrofoam (40b) does not need to use a separate vinyl because there is no fear of the cement water.

In addition, as shown in FIG. 7 (b), the filler 40 may be replaced with a water pad 40c in which a plurality of sealed water-filled water guns are formed. In this case, the filler 40 may be formed by irregularities between the water guns. The protrusions 31 may be formed, and the water pad 40c does not need to use a separate vinyl because there is no fear of cement water.

The uneven styrofoam 40b and the air pad 40c may be incinerated by injecting a flame into the air passage forming hole 32 to remove the filler 40 after the bottom layer 30 has been completely cured. By forming a through hole penetrating the bottom slab, the filler may be removed through the through hole.
